title: Pulmonary embolism caused by right atrial myxoma on FDG PET/CT.
abstract: Pulmonary embolism derived from the right atrial myxoma is a rare event and can be difficult to recognize. A chest x-ray image from a 48-year-old woman with shortness of breath revealed multiple pulmonary nodules, which suggested lung metastases. An FDG PET/CT was performed for further evaluation. The images showed that the lung nodules had variable but mild FDG activity in general. There was 1 additional large FDG activity in the right atrium. The subsequent studies demonstrated that the patient experienced pulmonary embolism derived from the right atrial myxoma.
